This is all-around great advice. I heard some similar things on Ricky Gervais' show After Life, and I wrote them down:

> It's worth sticking around to maybe make my little corner of the world a slightly better place.

> Happiness is amazing. It's so amazing, it doesn't matter if it's yours.

> You may not like living much, but you can make the world a better place. So don't give up, because then they've won. And they grow in numbers.
